Abstract: Elastic connection terminal for an electric switch or junction device, comprising an elastic loop placed on a conducting part and an auxiliary part capable of forming a stop for the end of the cable. The assembly and behaviour of the terminal are improved by placing an auxiliary part 30 in contact with the back of the support strip 18 of the conducting part 14. The part 30 is provided with at least on attachment element, for example a lug 34, engaged with the connection region of the support strip, and guide panels for the cable. The guide panels extend close to the connection area and they have a slope adapted to the curved shape of the loop 20 so as to guide it.

Abstract: A protection and control assembly includes a power terminal block having openings, and electrical switch devices having input side conducting connection strips and output side conducting connection strips that project from a horizontal connection area on the input side and output side, respectively, of the electrical switch devices along a vertical axis. The electrical switch devices are positioned adjacent to each other along a direction parallel to the vertical axis, and the power terminal block makes the electrical connection by clamping the output side conducting connection strips of a first electrical switch device with the input side conducting connection strips of a second electrical switch device.

Abstract: The invention relates to a protection and control assembly comprising a first and a second electrical switch device. Each device has a box (10,30) provided with input side (39b,19b) and output side (39a,19a) conducting connection strips that project on a horizontal connection area on the input side (34b,14b), and output side (34a,14a) respectively, of each box (30,10). The strips can be inserted in openings (44) in the removable power terminal blocks (40,50,60). The assembly comprises a common power terminal block (40) that makes the electrical connection by clamping the output side (39a) connection strips of the first electrical device with the input side (19b) connection strips of the second electrical device, thus providing a mechanical attachment between the two electrical devices.

Abstract: Electrical apparatus including a cap and having a connection screw terminal cooperating by way of a screwthreaded head with a screwthreaded hole in the cap. The screwthreaded hole has an unthreaded outer part accommodating most of the screwthreaded part of the screwhead. A captive clamping washer is provided to permit clamping of a conductor between the clamping washer and a fixed conductive part.

Abstract: A device is provided for snap fitting an electric apparatus on a support bar comprising, in a case, a housing containing a blade spring and opening into a groove in which one of the edges of the support bar may be engaged against the action of the blade spring. This latter is disposed inside the housing so as to exert a transverse force on said edge and has, at its end situated towards the edge, at least one fastening step of a hardness greater than that of the bar.

Abstract: An electric control device adaptable to a two state switching device is provided comprising two electromagnets disposed head to tail and each having a coil inside which a coil is slidably mounted, and two rocking levers which each comprise a first arm having a toothed sector and a second arm coupled to a respective core. The two toothed sectors mesh with a toothed pinion mounted for rotation in the case. This toothed pinion may be coupled to the operating shaft of a switching device.
